Hi guy. I need some help. Having a misfire on cylinder 4 in my 2000 chevy blazer 4.3L 2WD. I have spark and fuel. Compression is only 60 psi. Not sure where to go from here.

It has 265000 miles on it. I've had the truck for 7 years. Fortunately I haven't had to tear the engine down that far yet. Tomorrow I am going to take the head off that side. If it is a burnt valve is there anything in particular that I should be looking for or any handy tips you recommend?

Thank you for the insight. I will hook the air supply to it and start there. When I am listening for the leak should where should I be listening and more over where should the distributer be pointed to a closed exhaust valve on cylinder 4?

ARCO (and cheap gasoline) Gasoline. Pay me now or pay me later, Junk gasoline that allows for deposit build-ups. Same with engine oil changes. Who in **** needs an oil change sensor. When its BLACK it's too late.
Someone will be making money even if the OP does the work himself. (getting tired of all the female names men use here too.)
